Connor McLaughlin 845cd37835 DMA: Determine slice size based on whether pad is transmitting
Plenty of games seem to suffer from this issue where they have
a linked list DMA going while polling the controller. Using a
too-large slice size will result in the serial timing being off,
and the game thinking the controller is disconnected. So we
don't hurt performance too much for the general case, we reduce
this to equal CPU and DMA time when the controller is
transferring, but otherwise leave it at the higher size.

JIT optimizations and refactoring (#675)
* CPU/Recompiler: Use rel32 call where possible for no-args

* JitCodeBuffer: Support using preallocated buffer

* CPU/Recompiler/AArch64: Use bl instead of blr for short branches

* CPU/CodeCache: Allocate recompiler buffer in program space

This means we don't need 64-bit moves for every call out of the
recompiler.

* GTE: Don't store as u16 and load as u32

* CPU/Recompiler: Add methods to emit global load/stores

* GTE: Convert class to namespace

* CPU/Recompiler: Call GTE functions directly

* Settings: Turn into a global variable

* GPU: Replace local pointers with global

* InterruptController: Turn into a global pointer

* System: Replace local pointers with global

* Timers: Turn into a global instance

* DMA: Turn into a global instance

* SPU: Turn into a global instance

* CDROM: Turn into a global instance

* MDEC: Turn into a global instance

* Pad: Turn into a global instance

* SIO: Turn into a global instance

* CDROM: Move audio FIFO to the heap

* CPU/Recompiler: Drop ASMFunctions

No longer needed since we have code in the same 4GB window.

* CPUCodeCache: Turn class into namespace

* Bus: Local pointer -> global pointers

* CPU: Turn class into namespace

* Bus: Turn into namespace

* GTE: Store registers in CPU state struct

Allows relative addressing on ARM.

* CPU/Recompiler: Align code storage to page size

* CPU/Recompiler: Fix relative branches on A64

* HostInterface: Local references to global

* System: Turn into a namespace, move events out

* Add guard pages

* Android: Fix build

Connor McLaughlin 4798f35e40 Pad: Delay ACK after receiving byte
The controller routines in the BIOS seem to depend on this, if they
happen at the same time depending on what part of the code it was in,
it'll assume no controller is connected.
